热成像摄像机聚焦在脸部周边区域,那里的皮肤比较薄,可以轻易监测到温度变化。
The thermal camera focused on the region around the eye because the skin is thinner there, making its temperature changes easier to spot.
对于比热,这是一个比较简单的可测量,我们改变温度。
And then the heat capacity, which is this often a very simple thing to measure, you change the temperature.
首先,我们将整个房间的温度提高到比较舒适的70华氏度(大约是20摄氏度)。
First, let's raise the whole room's temperature to a comfortable 70 degrees Fahrenheit (about 20 degrees Celsius).
On the other hand, temperature, volume and pressure are variables that are much easier in the lab to keep constant.
另一方面,温度,体积和压强,在实验室中比较容易保持恒定。
T2 Is the temperature T2 in this process smaller or larger than if I were to do the process reversibly with the same endpoint pressure.
这里的末态温度,与经过可逆绝热过程,到达相同压强的末态温度相比哪个比较高呢?
Let me talk to you about temperature scales.
就可以比较前两个物体的温度。
